Boot splash resolution

Hello all.

When the nouveau modules is loaded during system start up, the resolution changes and looks really nice. Is there a way to replicate this using the official Nvidia driver?

I'm not sure, but probably not. The feature you refer to is KMS -Kernel Mode Switching.

I'd love it to work that way unfortunately neither the fglrx driver or the nvidia driver do not work this way. Maybe now that Linus has called out Nvidia things may start to change. ATI on the other hand, i doubt it.

I think that what you need is using vesafb with an appropriate resolution

You can install hwinfo over at at run it like so

hwinfo --framebuffer

If you use the nvidia driver then you have to use the vesafb for your framebuffer driver. Using the above command will tell you what resolutions your card supports using that driver, this is the output for my card.

Mode 0x0361: 1280x800 (+5120), 24 bits
Config Status: cfg=new, avail=yes, need=no, active=unknown

So we can see the maximum resolution available for my card is 1600x1200. To use it I would edit /etc/lilo.conf and change the VGA line to...

VGA = 0x034a

after you edit /etc/lilo.conf rerun "lilo" as root and you should be good to go.

Or - just as an alternative:
edit /etc/lilo.conf with
vga = ask
run lilo as root, reboot and get the list of supported framebuffer without installing hwinfo
